Application filed January 17,1885. Serial No. 153,137. (No model.)Patented in Belgium J une 23, 1884, No, 65,556, and in Italy June 3o,1ee4, No. 11,059. l

.To all whom it may concern:

-Be it known that I, WILHELM LORENZ, of Carlsruhe, in the Grand Duchy ofBaden and Empire 0f Germany, have invented certain new and usefulImprovements in Compound Projectiles, (which have been patented inlBelgium J une 23, 1884, N o. 65,556, and Italy J une 30, 1884, No.17,059,) of which the following is a specification.

This invention relates to the manufacture of compound projectiles; andit consists of a compound projectilel the core of which is melted ontothe covering shell, which shell is coated with tin or other metal. Thecore or shell, or both, are provided with guide-rings that are melted onthe same.

In the accompanying drawings, Figure 1 represents a vertical transversesection of a shell for my improved projectile. Figs. 2 and 3 arevertical central sections of my improved compound projectiles havingguide-rings in the form of caps. Figs. 4, 5, and 6 are vertical centralsections of projectiles with modilied forms of guide-rings. Fig. 7 is avertical central section showing the projectile in the Fi 8 is a sideView and section of another moditzled lform of a projectile with annular'guidegrooves; and Figs. 9, 10, and 11 are sections of modified forms ofprojectiles in which the.

guide-rings are made integral with the shell. Similar letters ofreference indicate correspending parts. l A My improved compoundprojectilesponsist, essentially, of a heavy metalcore or projectile anda. covering-shell of harder metal,which is united with the projectile insuch a manner that 'they form in use one ignited whole. The shells maybe made of one or more" parts. lhey are preferably made of steel,copper, brass, or other metal or alloy of metal possessing a high degreeof hardness and sullicient ductility. 'lhe shells are made, preferably,trom' disk-shaped blanks in Vdraw-presses, according to the metal or theform of shell. 'llhey may be cast in molds or turned inalathe, er madein any other suitable manner. rlhe shells S are ,rst cleaned on theouter and inner surfaces, in the usualmanner, by means of acid,andcovered at the outside and inside, er 'at the inside only, with acoating lof tin,-

zinc, or other metal, by any approved method; or they. are prepared inany other manner,

vso thatv the projectile, when introduced into least equal to thefusing-point of the metal of the projectiles, whereby the latter areunited at the moment of insertion with the shells. The metal of whichthe core is made may also be' poured in molten state intothe shells,whereby, also, the desired union between the core and shell 'isobtained. The .core may be compressed more or less after it has been4united with the shell, which pressing 'recommends itself when the coreshave been cast Kin the shells and after they have somewhat cooled oil".y 4

= For guiding the projectiles in the barrels of the rearms,the shells Sare either increased in thickness, asl at @Figs 4 and 10, or enlarged bybulging, as at r, Figs. 5 and ll, capro videdwith'one or moreguide-rings, 1', as in Figs. 6 and 7, or with a cap, ra, that is placedover the vbase of the projectile, asv in Figs. 2, 3, and 5. lo properlyinclose the core l), either the caps 1' or bottom disks, f, may be used,in' p Figsrl and 9. n

Fig. 8 shows a shell with annular guidegrooves r4. The guide-rings,caps, or bottom disks are also' coated with' tin. or other metal andmolded onto the core,either partly er eutirely.- ln the case of thecaps, theyv he I connected either at their inner .surface with the coreor at the periphery with the shell.

The melting together of the core and shell maybe accomplished dreh-andthen the guide ringsor caps specially melted on g or the cores, shells,and 'guide-rings or caps may loe united together at'on'eand the sametime and by one.' operation. y

dimensions and weight. The compound projectiles with hard shells .andhardened points and cores united thereto by melting are ca- -pablefo'thigh resistance and possess great force ci' penetration. As the shellscannot, on striking an object, get detached from the cores, break, orgive Way, and as the cores cannot crowd up or flatten, the compound projectiles differ advantageously from the projectiles heretofore known, inwhich the shells or coverings are not united with the cores, and

in which the shells, when striking the object, either crowd up or detachthemselves from the cores, so that they pass in detached parts throughthe soft parts o f the object and exert an injurious influence on thewounds caused thereby, while they can, owing to their form and size, beremoved only with difficulty from- .the wounds. Another advantage is,that the cores and shells partake of asimultaneous rotation, whereby abetter trajectory and a greater accuracy in hitting the object areobtained.

Still another advantage is, that by the tinning f or other preparationofthe shells-Tas, for instance, in steel shells-the corrosion ofthesameis prevented and blood-poisoning obviated when they penetrate thelieshy parts, which would surely take place with unprepared and fragileshells of steel, copper, brass,l

or other metal.

Having thus described my invention, I clalm as new and desire to secureby Letters Patent- 1. A compound projectile the core of w h1ch is meltedto the coveringshell, substantially as set forth.

' 2'. -A compound projectile the core of which is melted to thecovering-shell, 4which latter is coated with tin or other metal,substantially I as set forth. l

3. A compound projectile composed of a core and covering-shell, thefermer being melted to the shell, andg'uide-rings melted to the coreor'shell, or both, substantially as set forth. t
